It is small relative to the size of other contributions.
You claimed that the problem of climate change can be "basically solved" by preventing billionaires and millionaires from flying on private jets. You are either suggesting a total emissions reduction of <5% is satisfactory, in which case you would be a) wrong and b) admitting that the global contribution from aviation is indeed relatively negligible, or you are suggesting that the 5% figure is wrong and aviation in fact makes up a much higher percentage of global emissions in which case you are also wrong.
